Oh that looks like it could hurt when he has to go, stings I bet. I know with Wilson during the winter months I have to clean his wee wee periodocially. During the summer he's in his pool every day so that keeps it clean. Bulldogs as you've discovered cannot bend to clean certain areas that most dogs can. Wilson doesn't get too much discharge, he's neutered but he does get some so I check him. Curious to know what the vet says. Seems like the first infection never had enough time to heal? Poor guy.
